I may be one smoot short of a bridge and all, but...

So, the Globe is reporting on the City of Boston requiring abutting property owners to pay half of the cost of replacing asphalt sidewalks with concrete sidewalks if they wish for their street to have durable, attractive, even-surfaced sidewalks like most streets have.

Meanwhile, the Neighborhood Access Group is still fighting to have the city stop constructing and maintaining brick-and-mortar sidewalks, which are trecherous for anyone with poor balance and/or who uses a mobility aid, and to instead use (cheaper) concrete sidewalks in their place. The group has been successful in stopping the construction of some specific brick sidewalks, but they are continuing to be constructed throughout the city.

Does anyone else see where the city could get money for replacing asphalt with concrete?
